property value setting
I have a build.xml file in which there is a property value "PW90". And this value is initialized through the command line, such as: ant -f build.xml -DPW90="...".
However, I just realize that 95% of time, the value is same. So I am just wondering if I could set a default value for this "PW90" inside the build.xml. Only when "-DPW90=.." is specified on the command line, then it will be overwritten by the input value.
I am using ant 1.7 on Linux box.
Thanks for the tips.

yes. <property name="PW90" value="something"/>

Anything set on the command line ovrrides any definitions in your build
file...

Any properties set on the command line are always set first before any
task is run in ant.
Go ahead and set PW90 in a property to its default value.
Anytime you use -DPW90="..." on the command line it will be set first
and your default variable will not override it.
